Great East Window: Located above the high altar of The Cathedral of All Saints, the Great East Window consists of a fourteen-part rose window mounted in stone tracery above five large lancet panels. The leaded stained glass panels were designed and fabricated by Clayton and Bell of London, England, one of the great stained glass designers of the period, who also designed and fabricated the ten windows of the choir clerestory. Erected in two phases between 1884 and 1904, The Cathedral of All Saints contains one of the finest collections of Clayton and Bell windows, as many contemporary Clayton and Bell windows in London were destroyed as a result of bombing raids during World War II. By the 1990s, mortar in joints between the various stone blocks of the window tracery had failed, and daylight could be seen where caulking was missing between leaded glass panels and the stone tracery. Lead cames had also deteriorated and support for individual leaded glass panels had weakened, leading to deflection and glass breakage. The project consisted of a comprehensive restoration of the leaded stained glass panels and repairs to the stone tracery. The panels were removed to a conservator’s studio where they were documented and carefully disassembled. Colored glass was cleaned, broken pieces repaired, and missing pieces carefully color matched for replacement. The reconditioned glass was reinstalled in new lead cames, and each panel reinforced to reduce future deflection. The stone tracery was repointed to stabilize it in place. Utilizing existing wire-glass protective glazing located at the exterior side of the tracery, the restored leaded glass panels were reset in the repaired stone tracery.

Roof & Masonry: A multi-phase project was undertaken to repair roof leaks and masonry deterioration at the exterior of this Gothic revival style cathedral. Constructed in two phases between 1884-1888 and 1902-1904, the exterior walls of the cathedral are faced with orange and brown sandstone on brick back-up walls, and the building is roofed with a mix of slate shingle and sheet metal roofing. The Cathedral is listed in the National Register of Historic Places. Problems included deteriorated and failing roofing and flashing systems, open mortar joints, and stone displacement due to water infiltration and freeze-thaw movement.

Following the preparation of a thorough existing conditions assessment, the project was phased over several years. Deteriorated asphalt shingles and sheet metal roofing were removed and replaced with new standing seam coated stainless steel and sheet copper roofing. Slate roofing was removed and replaced with new slate shingles that match original slate, with copper flashing. Following documentation, the facing stones on several buttresses were disassembled to uncover damaged and partially collapsed brick backup walls. The brickwork was completely rebuilt and stone facing blocks reinstalled to match original bonding patterns.
